HelloWords is a language‑learning app that focuses on building vocabulary through interactive word games, AI‑generated contextual stories, and a spaced‑repetition review system. Users practice vocabulary with drag‑and‑drop, matching, and multiple‑choice games, then see the words used in personalized stories that reinforce meaning and usage. The app schedules review sessions based on the Ebbinghaus forgetting curve to improve long‑term retention, and it tracks progress after each study session. Learning is designed for short, daily sessions of a few minutes, making it suitable for busy schedules.
